Key materials and structural design in flexible and stretchable zinc-air batteries

Sustainable zinc–air battery chemistry: advances, challenges and prospects

“…In recent years, many groups have summarized the development of ZABs, including oxygen electrocatalysts, electrolytes, and Zn anode protection protocols. [18][19][20][21][22][23][24][25] Nevertheless, special attention and deep discussion on sustainable ZAB chemistry have not been reported to date. In this review, we focus on the latest progress and challenges associated with sustainable ZAB chemistry (Fig.…”

Strategies Toward Stretchable Aqueous Zn‐based Batteries for Wearable Electronics from Components to Devices

“…Different from the above Zn‐ion batteries, stretchable Zn‐air batteries require sufficient gas transmission capability due to the oxygen evolution reaction and oxygen reduction reaction occurring at solid‐liquid‐gas interface. [ 114 ] The stretchable cathodes loaded with oxygen catalysts can be classified into two categories: 1) catalysts loaded on carbon cloth or other stretchable substrates; 2) self‐supporting stretchable cathodes. [ 115 ] The stretchable cathode usually possesses a porous structure to promote the kinetics processes of the oxygen reaction.…”

High-coordination Fe–N4SP single-atom catalysts via the multi-shell synergistic effect for the enhanced oxygen reduction reaction of rechargeable Zn–air battery cathodes

“…Rechargeable zinc-air batteries (ZABs), as a new generation of green energy conversion devices, have been extensively explored due to the abundance of the zinc anode and high theoretical energy density (1086 W h kg À1 ). [1][2][3][4][5][6][7][8] However, their large-scale application is still restricted by the sluggish kinetics of the oxygen reduction reaction (ORR), as well as the high-cost and scarce benchmark Pt/C catalysts. 9,10 Alternatively, singleatom catalysts (SACs), prominently featuring M-N x sites (where M refers to Fe, Co, Ni, etc.)…”
